Rotovap is an important equipment, used mainly in chemical laboratories to gently remove solvents from given samples from the process of evaporation. Henan Lanphan Industry Co., Ltd is a professional manufacturer of this equipment and intends to provide laboratories with all information and assistance in using it in the most efficient manner. This is the reason why they are explaining about using the equipment in a proficient manner for chemical labs to achieve the best results without fail.
The science equipment manufacturer publishes an article on using the rotary evaporator to efficiently distill solvents. According to the spokesperson of the company, the information will allow laboratories to use the apparatus with efficiency to achieve great results. The article will also detail out the correct way to halt the apparatus. The spokesperson reveals that one should, at first, must learn about the equipment itself. It consists of four parts, which are water or oil bath, rotary rotor, a glass condenser and flasks. The article reveals simple steps of using and halting the apparatus, which are easy to learn and practice in laboratories.
For using the apparatus, the first step to follow is to warm up the water/oil bath and cooling the glass condenser. Then, one needs to fix the bump trap and the flask tightly, using a clamp. The spokesperson maintains that a loose setup may not be a safe idea for filling it up with heavy solvents. In the next step, the rotary rotor should be started at a fixed speed. However, it should be kept in mind that the speed must be fast enough to so that a balanced thin film is formed on the inner surface of the flask. In the next step, one should start the Vacuum Pump and the stopcock on the glass condenser must be closed till then a whistling sound is not heard. The sample is then left to spin under vacuum for one minute or so, and then it will start boiling very soon.
After that, one should observe the operation for one or two minutes, and open the stopcock, if there is any danger. Then, the process needs to be repeated so that the solvent is streaming out from the condenser. One should keep checking the operation occasionally to make sure that the apparatus is functioning properly. With this article available on Lanphan Industry’s website, one can easily learn how to use rotovap. One can also learn about the correct procedure of halting the apparatus.
